If you get some fresh pawpaw seeds now, store them damp in the fridge for
100 days, plant them in pots in January, set them out a month after the
last frost, you should have first blossoms in 2005, and first fruit in 2006.
Fruit set is much greater with at least two non-clone trees.
Grafting a non-clone onto a pawpaw will allow the same out-cross
pollination as having separate trees.
